【摘要】：水环境污染问题一直以来都是社会关注的焦点之一。近年来,嘉兴水路运输市场逐步成熟,危化品水路运输量逐年递增,如何应对危化品水路运输泄漏突发性情况,最大限度减少污染,防止泄漏物对当地水质以及周边环境的影响显得至关重要。论文在查阅国内外泄漏扩散分析及应急系统研究进展,并对嘉兴内河危化品水路运输情况、主要运载危化品物化特征、主要危害进行分析的基础上,选取甲苯等为代表物质,借助河流完全混合模式、河流一维稳态模式、河流二维稳态混合模式和河流PH模式四种数学扩散模型,对危化品泄漏扩散进行扩散模拟,合理选取危害程度评价参数,建立危化品泄漏事故危害程度评价标准并分类简析了事故现场控制及危化品水路运输泄漏事故发生后的应急处置措施,为嘉兴内河水上危化品运输泄漏事故应急处置以及水环境影响的控制提供了新思路。
[Abstract]:In recent years, Jiaxing waterway transportation market has matured gradually, the quantity of dangerous chemicals waterway transportation has been increasing year by year, how to deal with the sudden leakage of dangerous chemicals waterway transportation, Minimization of pollution and prevention of leakage impacts on local water quality and the surrounding environment are essential. On the basis of consulting the research progress of leakage diffusion analysis and emergency response system at home and abroad, and analyzing the waterway transportation of dangerous chemicals in Jiaxing River, the main physical and chemical characteristics of dangerous chemicals and the main hazards, toluene is selected as the representative material. With the help of four mathematical diffusion models, river complete mixing model, river one-dimensional steady-state model, river two-dimensional steady-state mixing model and river PH model, the diffusion simulation of dangerous chemicals leakage and diffusion is carried out, and the hazard degree evaluation parameters are reasonably selected. The evaluation standard of hazard degree of dangerous chemicals leakage accident is established, and the emergency disposal measures after accident site control and dangerous chemicals waterway transportation leakage accident are simply analyzed. It provides a new idea for the emergency disposal of the leakage accident and the control of the water environment impact in Jiaxing River.
